To all whom it may concern:

Be it known that I, GEORGE A.

States, of Cook and State a citizen of the United Chicago, in the county JoHNsoN, residing at of Illinois, have invented a certain new and useful Improvement in Draft-Rigging for Railway-Cars,-

full, clear, concise, and exact of which the following a description,

reference being had to the accompanying tion.

' 1 0 drawings, forming a part of this specifica- My invention relates to draft rigging for railway cars.

The object of my invention is to provide 15 a draft rigging operation, and power.

' In the drawings partly in horizontal draft rigging. embodying Fig. 2 is a side elevation. inclusive are enlarged details,

a plan view for railway cars of eflicient one of graduated resisting Figure 1 is a plan view section of a railway my invention. F1gs. 3 to 5 both Fig. 3 being of the. compression resisting member and front follower partly in longitudinal section. the front follower. Fig. 5 view of the front follower.

Fig. 4 Is an end view of is a perspective Figs. 6, 7 and 8 illustrate a modification, Fig. 6 being a plan view partly in longitudinal section of compression resisting member and front folthe lower, Fig. 7 an end view of the front follower, and Fig. 8 a perspective front follower.-

In the drawings sills or members of the car the draft rigging is attached,

11 the rear front stop members,

view of the 9, 9 represent the draft frame to which 1.0, 10 the stop members, 12, the draw bar, 13 the draft yoke, 1 1

the end sill, 15 the buffer block, bar carry iron-all tion.

16 the draw of well known construc- 17 is a tie and draft yoke carry plate and 18 the shell, which is hollow and preferably cylindrical in shape or circular its rear end by in cross section, open at its forward end and closed at the preferably integral trans:

. verse rectangular-plate 19, which serves as a rear follower.

the internal friction The shell is provided with face 20,- and contains the springs 21 and 22,. which are seated at their rear ends against the rear end of the friction shell.

a 23, 23 are the segmental friction shoes,

preferably three in number, 5 wedge.

and 24' the construction shown in.

25 is the front follower comprising a substantially rectangular plate 26 provided on its forward face with the central recess 27 to receive the head of the connecting rod 28. The wall 29 of the recess 27 forms a rearwardly extended boss 30 to engage the wedge 24. Surrounding the boss 30 in the rear face of the plate 26 is the groove 31 in which i the forward end of the preliminary spring 32 is seated, the said spring being seated at its rear end against the forward ends 33 of the friction shoes 23. Outside the groove 31 in "the rear face of the plate 26 is provided a shoulder 34: with which the forward ends 35 of the friction shell engages upon full compression of the parts within the shell, as illustrated in Fig. 3 of the drawings. The front follower further comprises a rearwardly extended hood 36, which surrounds the forward end of the friction shell 18 and is in sliding engagement therewith. The boss 30 is sufiiciently rearwardly extended to permit a space 37 between the wedge 24 and the said boss of sufficient length to permit the compression of the preliminary spring 32 before the boss 29 engages the wedge 24. Upon the movement of the draw bar and the consequent compression of the gear the preliminary spring 32 is first compressed, and then the boss 29' engages the wedge 24, bringing into action the friction shoes 22 and the springs 21 and 22. p

In the modification illustrated in Figs. 6, 7 and 8. of the drawings the shell 38, the springs 39 and 40, the friction shoes 50, the wedge 51, the connecting rod 52 and the preliminary spring 53 are all identical in construction and operation with the similarly resignated parts of the approved forms of Figs. 1 to 5 in the In the modification the front 54: consists of a substantial rectangular plate 55 provided on its forward face with the central recess 56-to receive the head of the connecting rod,.and provided with the rearwardly extended boss 57 to engage the wedge '51. Surrounding the boss 57 is the groove 58 in which the preliminary spring 53 is seated at its forward end. Said spring 53 engages rear end.

I claim:- 1. In a friction draft rigging, the combination of the draw bar, draft sills, stop drawings. followerthe friction shoes at its shell, with a front followerprovi'ded with e 4 reerwardly extending hollow member to receive the front end of the friction shell therein, and a boss within said member ongaging the wedge, and a spring seated at its forward end around said boss and at its rear end against said friction shoes.

2. In a frietion draft rigging, the combination'of the draw bar, draft sills, stop members, draft yoke, friction shell, and e wedge, friction shoes and springs within the shell, with a front follower provided upon its rear face with a recess to receive the friction shell and a boss to compress the Wedge within the shell.

3.. In a friction draft ri ging, the combinatioh of a draw bar, dra t members, stop members, a friction shell, friction devices, springs, and a wedge within the shell, with a front follower provided with a reerwardh extending hood in sliding engagement with the shell, and a spring interposed between the front follower and the friction devices.
